SONAR Cayenne DRL LED units - wiring questions...

[Sunnykent]

Afternoon all, firstly let me start off by acknowledging these are cheap aftermarket DRL LED headlights so please don't use this thread just to slag me off for at least trying to get these working.

 

I am trying to fit them to a UK Cayenne which yes is RHD but I will actually be using them in the EU which I spend a lot of time in Spain and Portugal so the beam is not an issue.

 

My problem is that whilst everything seems to work, the exact bulbs that should illuminate at the correct switch don't

 

I have the basic Halogen headlights - NOT XENON

 

On my attached photo you will see that with the stock headlights, light switch position 1 turn on the small sidelight. Light switch position 2 turns on the small sidelight AND the TOP H7 bulb. Then if i push forward the indicator lever that turns on the bottom two bulbs which I also think are H7. 

 

Firstly is everyone else's the same setup?

 

If thats all correct now let me explain what happens with the new SONAR DRL LED headlights......

 

Light Switch position 1 : WHITE LED lights strip illuminates

Light Switch position 2 : Nothing changes - no further light comes on at all - I would have expected the fake projection bulb H7 to illuminate but it doesn't

Push forward the indicator stalk : Both the fake projection bulb illuminates H7 as well as the smaller H1 one very bright bulb.

 

No matter what I try on both sides the larger fake projection H7 bulb will not illuminate until I goto High Beam with the indicator stalk pushed forward but then both the H7 AND H1 illuminate. 

 

This cannot be right surely??

 

I have checked the pinouts as best I can at this stage and it seems the stock H7 top bulb are in a different place to what I see on the new SONAR DRL LED headlights. In fact the pinout actually goto a small cable that plugs into two brown cables and goes to something at the bottom right of the fake projection bulb.

 

Has anyone on here in the UK ever fitted these and if so did you encounter this issue??
